🐢Olive ridley sea turtle

Lepidochelys olivacea (Eschscholtz, 1829)

丽龟(學名:Lepidochelys olivacea)是海龜的一種,又稱太平洋丽龟、榄蠵龟、橄龟、姬賴利海龜。牠最大的特色是灰黑色心型背甲,外觀像一顆大橄欖而得名為欖蠵龜。种加词 olivacea 意为“橄榄状的”、“卵圆形的”。成龜體長達62到72公分,體重約45公斤。是世界上現存七種海龜中體型最小的。 丽龟是肉食性動物,食物包括各種魚類、軟體動物、甲殼類等。分佈範圍以熱帶69海域為主,偶而也會在溫帶海域中看到牠。 丽龟母龜在繁殖期時,習慣於日間集體上岸產卵,個體母龜每季產下1到3窩,據南美蘇利南的統計資料每窩大約平均116顆 (30至168) ,而太平洋東的統計資料顯示每窩大約平均105 (74–126)。龜卵正常需45至51天才會孵化,幼龜剛出生時,長約43公厘,體重約24克左右,至少要12到30年才达到成年期。 由於丽龟習慣於白天集體上岸產卵,一次可能多達百隻以上規模,場面相當壯觀,世界各地以印度和墨西哥兩地海岸,可以看到丽龟產卵的生態畫面,印度的奧利薩省就曾出現超過上萬隻丽龟產卵的鏡頭 (页面存档备份,存于互联网档案馆)。墨西哥海灘上也曾出現,此習性造成盜獵者往往肆無忌憚的殘殺丽龟。他們盜獵的原因是取得龜蛋,據稱丽龟的龜卵是春藥的主要成份。
